Find LCM of 396,792,847,842 with Prime Factorization
2 | 396, 792, 847, 842 |
2 | 198, 396, 847, 421 |
3 | 99, 198, 847, 421 |
3 | 33, 66, 847, 421 |
11 | 11, 22, 847, 421 |
1, 2, 77, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 1 x 2 x 77 x 421 = 25674264
Therefore, the lowest common multiple of 396,792,847,842 is 25674264.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
396 x 792 x 847 x 842 = 223674187968
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
847 : 1, 7, 11, 77, 121, 847
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,792,847,842, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
792:2x 2x 2x 3x 3x 11
847:7x 11x 11
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 11x 11 = 8712
Therefore, the value for common factors is 8712.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 223674187968/(1x8712)
LCM = 223674187968/8712
LCM = 25674264
Thus, we can understand that the LCM of 396,792,847,842 is 25674264.
